INSTRUCTIONS OF THE INVENTION: FIELD OF THE INVENTION The present invention relates generally to a sprinkler assembly suitable for use in connection to a source of pressurized transport liquid, and the present invention is suitable for mounting to a chemical liquid container, The chemical liquid is introduced into the transport liquid stream as a siphon in the open state of the valve. [Prior Art] A plurality of sprinkler assemblies are mounted to a chemical liquid container and attached to the end of a hose for transmission through the Venturi effect (V e η ΐ uri E ffect ) or by providing an air gap , taking a quantity of chemical liquid into the water flow path. A manually operated rotatable valve is designed to open the sprinkler when the transfer liquid interface and the product interface are coupled, to close the sprinkler by separating the transfer liquid interface and the product interface, and to prepare a rinse discharge liquid that is coupled to the transfer liquid path . When the chemical liquid product is drawn into the liquid transport stream, it is important that the sprinkler is in an open state to bring the container opening into contact with the atmosphere. According to U.S. Patent Nos. 6,5, 8, 7, 7 6 and 6, 6 7 2, 5 2 0, and No. 6 0 / 5 1 5 , 4 1 6 , the control of the above opening is in the sprinkler The rotating wide door inside the outer casing valve allows the liquid to be transported into the chemical liquid container without the need to seep through the opening, which is of course the most undesirable condition. If such percolation is allowed, when the selected chemical agent is used to spray the shrubs and grasslands in the garden, the chemical liquid will be diluted so that it loses its usefulness. The present invention as set forth in the aforementioned related application solves this problem by controlling the separation of the transport liquid/chemical 5 312XP/invention specification (supplement)/93-12/93125328 1257880 liquid by opening and opening, thereby avoiding The dilution problem described above. Providing another solution, with a simple structural opening that is easy to use and assemble, yet highly efficient to provide reliable opening control discharge, and to avoid any possible transport of liquid percolation into the container when the opening is open, this is Expected. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a hose end sprayer assembly having a rotary valve for connecting a transfer liquid interface passage and a product liquid interface when the sprayer is opened. At the opening, and simultaneously opening an opening in the sprinkler cover. An external opening control member is mounted on the outer cover, and the opening and closing openings are respectively opened and closed by the valve to engage the outer cover with the valve opened and closed. The external opening control may include a rocker arm having an open gasket for moving in and out of the opening path, and may include a cam surface or the like to engage the protrusion by the upper protrusion when the valve is rotated. Affects the swing of the opening between the open and closed positions. Other objects and modifications can be made in accordance with the present invention and in conjunction with the accompanying drawings. [Embodiment] The same component symbols in the drawings are the same and corresponding parts of the respective viewing surfaces, and the sprinkler assembly according to the present invention is generally indicated as 1 0 in Figures 1, 3, 5 and 6, although It is to be understood that the rotary valve 1 1 (Figs. 5, 6) is not shown in Figs. 1 and 3, and the opening control member 12 (Fig. 2) is shown for clarity and not shown in Fig. 1. 6 312XP/Invention Manual (Repair)/93-12/93125328 1257880 The sprinkler assembly comprises a cover 13 similar to that shown in U.S. Patent No. 6,3,8,8,8,5, which is incorporated by reference in its entirety. The outer cover includes a conduit 14 having an anti-siphon assembly 15 at its end and including a closed end 16 to mount the assembly 10 to a court tube (not shown) or One end of the analog piece. The outer cover further includes an end ring 177 which is engageable with an annular opening 18 of the container closure 1 9 to support the sprinkler assembly on the neck 2 1 of the container (not shown in the figure) The outer cover further includes a transverse aperture 2 2 (Fig. 4) 'with or without a back wall 2 3 . And, the outer cover may be provided with an arched wall 24, with indicators, as shown (0 N ) and closed (0 FF ) to assist in the use of the opening and closing of the door valve, which will be further explained in the following description. The sprinkler cover is substantially identical to that disclosed in the sixth and third paragraphs, and is rotated. The valve 1 is substantially identical to that disclosed therein. The swing door is assembled in a suitable position as shown in Figures 5 and 6, which comprises a cylindrical outer wall which can be closed at one end 26. The valve is provided with a transfer liquid conduit 2, a cylindrical valve The diameter extends and has a liquid interface conduit 2 extending in a radial direction, and is connected to the conduit 27 at the opening. Rotating and having a rotating handle 29 or the like for the operator to the central axis Rotating the valve with an indicator bar 3 1 or an object The radial direction extends outwardly, and it is combined under the partial wall 24 as shown in Fig. 5 and the corresponding position of the rotating valve. The rotary valve can be manually rotated between the open and closed positions, as shown in Fig. 6. It is indicated that the flow from the opened garden hose will pass through an interface channel and transfer liquid in the conduit 14] 2XP/invention specification (supplement)/93-] 2/93125328 Lidi ° One meets) ° with the above ones. The phase-acting valve 25, which is gripped along the chemical valve, is similar to the pressurized water conduit 7 1257880 2 7, which is also disclosed in the application No. 60 / 5 1 5, 4, 16 , the complete disclosure Specifically incorporated herein by reference, it includes a Wendeli section that is formed as the inner diameter decreases, as it rotates the valve in the open position, along which it moves to limit the flow of the transport liquid. The interface conduit also has a section that has a substantially fixed radius greater than the minimum radius of the Wendley section. At the junction between these sections, one of the interface conduits or ports (not shown) from the housing will be attached thereto. Such a catheter or cartridge, as shown in Figures 6, 3, 8, 8 8 5, is coupled to a water tube extending into the container. Therefore, as the transport liquid flows along the Wanderley section, the pressure of the transport liquid stream drops because the chemical product is absorbed into the weir pipe and is introduced into the transport stream through the product conduit/intrusion. The chemical product that is introduced into the transport stream will be mixed therewith and discharged through the open end of the discharge passage (shown as No. 6, 3, 8, 8 8 5) in the outer casing of Fig. 6 and the conduit 27 . A rotatable nozzle (not shown) may be provided at the front end of the sprinkler assembly to direct the flow of mixed liquid to the target. Accordingly, the rotary valve is selectively rotatable within its bore, and when the open position of the discharge passage in the outer casing is shown in Fig. 6, the transfer liquid interface passage in the conduit 14 is connected to the liquid product port located in the outer casing. Also, the valve can be selectively rotated to the closed position shown in Figure 5, at which point the transfer liquid interface passage is not coupled to the liquid product port. Furthermore, the details of such selective opening/closing positions of the rotary valve are detailed in the patents Nos. 6, 3, 7 8 , 7 8 5 and 6 0 / 5 1 5, 4 16 , for further details. The description is already in it and will not be presented in this article. According to the invention, the opening of the container provides an opening 埠3 2 (Figs. 1 and 7) which is located directly inside the housing and is connected to the interior of the container and is open to the atmosphere. 8 312XP/Invention Manual (Supplement)/93-12/ 93125328 1257880 Touch. According to the present invention, by providing a control member 33, the opening control is external to the rotary valve and the transverse bore, as shown in detail in FIG. 2, in the form of an arched rocker arm 34 having an open seal Plug 3 5 is at one end. Also, the arched rocker arm may have a cam surface 3 7 at its outer edge 36 that is formed adjacent the other end thereof. A pair of flanges 3 8 extending outwardly from the end of the rocker arm may be provided for positioning the arched rocker arm beyond the outer casing and parallel to the transverse cylindrical wall 319 The wall is enclosed by a diameter of 2 2 to accommodate the rotating valve. Further, the outer cover may be provided with a protrusion 41 with a barbed outer end, as shown in the detail of Fig. 7, in the assembled position of the opening control member in Figs. 5 and 6, protruding between the flanges 38, thereby causing The barbs 42 extend in the stop means 43 on the inner wall of the flange 38, which will facilitate quick, easy and secure assembly of the arched rocker arms in position during assembly. In this position, the sealing plug 3 5 is disposed coaxially with the opening 埠 3 2 (Fig. 7). Also, when placed in the proper position, the inner edge 44 of the rocker arm supports a pivot pin 45 which extends outwardly from the direction of the cylindrical wall 39 of the outer cover. In operation, the valve is turned to the open position of Figure 6, and the bottom surface 4 6 of the handle 29 extends outward from the cylindrical wall 3 of the outer cover to support the cam surface 3 7, as shown by the phenomenon in FIG. The rocker arm 44 of the opening control member is caused to rotate about the pivot pin 45, causing one end thereof to move downward, and the other end thereof is moved upward in one direction, and the opening sealing plug 35 is also moved in this direction. Leave the opening 埠32 to open the opening.
